一种基于多SDN控制器的交换机迁移机制
A Switch Migration Mechanism Based on Multiple SDN-controllers
摘要
Abstract
In order to solve the issue of scalability in SDN (Software Defined Networking) control plane,the multiple SDN-controllers architecture with logical centralization and physical distribution is put forward in the industry. However,it cannot dynamically adapt to the change of traffic in the network and causes a load-imbalance among SDN-controllers due to the statically configured mapping between a SDN-controller and a SDN-switch. In order to solve the problem above,the load is needed to be monitoring and sharing between SDN controllers,and a dynamic migration mechanism based on multiple SDN controllers is proposed which can seamlessly migrate a SDN-switch to a normal SDN-controller or that with less load,avoiding the single point faulure or high load of controller during the event of controller failure or overload. A prototype system based on Floodlight is built. Experimental results show that the proposed method a-chieves a better load balancing between controllers,reduces the response time of the Packet-in message,and improves the performance of the whole system.关键词
